Math question: What is the sum of 38, its square root, and the product of its digits?

To find the sum, we start by calculating the square root of 38, which is approximately 6.164. Next, multiplying the digits of 38 (3 and 8) gives us 24. Now, adding 38, 6.164, and 24 together, we get a sum of 68.164.

Math question: What is the sum of 38 and its double when multiplied by 5 and divided by 2, subtracted from 100, and then divided by 4?

The sum of 38 and its double is 114 (38 + 2*38 = 38 + 76 = 114). When multiplied by 5, it becomes 570 (114 * 5 = 570). When divided by 2, it remains 570 (570 / 2 = 570). Subtracting 570 from 100 leaves us with -470 (100 - 570 = -470). Finally, dividing this by 4 gives us -117.5 (-470 / 4 = -117.5). Therefore, the answer is -117.5.

Question: What is the sum of 38 divided by 2, subtracted from 3 raised to the power of 2, times 10, plus the square root of 38?

To find the solution, we start by dividing 38 by 2 to get 19. Then, we raise 3 to the power of 2, which is 9. Multiplying 9 by 10 gives us 90. Now, we calculate the square root of 38, which is approximately 6.1644. Adding this square root to the above result of 90, we get 96.1644 as the final answer.
